XVILLIAM T. DECKER, OF LEHIGH TANNEBY, PENNSYLVANIA.

MOWING MACHINE CUTTER.

SPECIFICATION forming part of Letters Patent No. 35 6,574, dated January25, 1887.

Application filed July 22, 1886. Serial No. 208,722. (No model.)

To aZZ whom it viz/any concern.-

Be it known that 1, WILLIAM T. DECKER, of Lehigh Tannery, in the countyof Carbon and State of Pennsylvania, have invented a new and ImprovedMowing- Machine Gutter, of which the following is a specification,reference being had to the annexed drawings, forming a part thereof, inwhich- Figurel is a plan view of myimproved mowing-machine cutter,showing devices for connecting it with the cutter-bar. Fig. 2 is avertical longitudinal section taken on line a: :0 in Fig. 1. Fig. 3 is adetail perspective viewof one of the eccentric studs. Fig. 4 is a detailperspective view of one of the eccentric washers, and Fig. 5 is a detailperspective view of one of the countersunk washers Similar letters ofreference indicate corresponding parts in the different figures.

The object of my invention is to provide a simple and eflectivedevicefor securing the cutter-sections of niowingmachines to the cutterbars,sothat they may be readily applied and removed for sharpening andrepairs.

My invention consists in a cutter-bar pro vided with series of revolublestuds having eccentric edges, and series of eccentric washers placed onthe studs, the studs being secured in holes in the cutterbar at suitabledistances apart for receiving the cutter-sections, and in thecombination therewith of cutter-sections having apertures and shouldersfor engage,

ment by the fasteners, all as hereinafter more fully described.

The cutter-bar A is provided at suitable intervals with holes, in whichare placed studs B, having shouldersa, which bear upon the upper surfaceof the bar. Each stud B is provided with a hat eccentric head, I). Theholes in the cutter-bar in which the studs B are inserted arecounterbored to receive the couir tersunk washers 2', and the lower endsof the studs are riveted in the said washers. Upon each stud B, betweenthe eccentric head I; and theupper surface of the cutter-bar A, isplaced an eccentric washer, c, which corresponds in size with theeccentric head I) of the stud'B. Each head I) is provided in one edgewith a V-shaped notch, d, and is pierced near its oppositeedge with ahole, 6, the notch d and hole a serving to receive the wrench by whichthe stud Bis turned.

The studs B are arranged in pairs at suitable distances apart forreceiving the cutter sections 0. The cutter-sections C- are stampedorswaged, and provided with apertures f, near opposite edges at the heelof the cutter, and between the apertures f there is an elevated portion,9, having in opposite edges concave recesses h, for receiving theeccentric heads 2) of the studs B. The cuttersections 0 are placed inposition on the cutter-bar A, when the eccentric heads 1) correspond inposition with the eccentric washers c. The cutter is secured in theposition of use by turning the studs B so as to cause the eccentricheads b to reach over the upper surface of the cutter and bear againstthe edges of the elevated portion g. Arranged in this way the cuttersection may be readily placed in position and firmly secured, and it maybe easily released from the cutter-bar and removed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent. is-

1. The combination, with the cutter bar A, of series of studs B,provided with eccentric heads Z), series of eccentric washers c, placedon the studs B, between the eccentric heads I) and the cutterbar A, andcutter-sections 0, having apertures f, adapted to receive the cocentricheads]; and washers e, substantially as shown and described.

2. The combination of the bar A, the studs B, provided with shoulders aand eccentric heads b, the eccentric washers c, placed on the studs B,between the eccentric heads I) and cutter-bar A, and cutter sections 0,provided with apertures f, and the elevated portion g, having concaveedges h, substantially as shown and described.
